Application liled November 19, 1902. Serial No.1131,940. (No model.)

To all whom it may concern:

Beit knownthat I, FINLEY ACKER, a citizen of the UnitedStates, residingin the city and countyof Philadelphia,State ofPennsylvania, haveinvented new and useful Improvements in Codec-Urns, of which thefollowing is a specication.

My invention consists of a codec-urn which is composed of an urnproper,'a vessel for receiving ground coffee, the same having a per;vcolator and water-spraying device therein, a chamber for measuring theamount'of water desired to be converted into iiuid coffee, and a tankfor primarily boiling the water from which t-he coffee is to be made,the parts being hereinafter described and the novel fea tures of thesamebeing' pointed out in the claims.

Figure l represents a vertical section of a coffee-urn'embodying myinvention. Fig. 2 represents a side view of a detached portion thereof.tion on line w as, Fig.i 2. Figs, 1i and 5 represent top views ofdetached portions in dierent positions. v

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a tank, thesame being adaptedfor primarily receiving water, and is provided with a coil A', ofsteam-pipe, or an electrical or other device whereby the water in saidtank may be boiled. Connected with said tank is a vessel B, which is incommunication with said tank A by means of the valved pipe C, saidvessel having a heating or boiling device B' and a gage D for indicatingthe height of water in said vessel, said vessel serving to measure thewater for the quantity of fluid coffee it is designed to make, it beingalso provided with a vent E, the same being open to the atmospherefor-evident purposes. f

F designates what I term a codec-maker and which lconsists of acylindrical or other shaped receiver G' inl com munication withthechamber B by means of the pipe H. At the base of said receiver is thevalved pipe J, which is connected with the urn K. Within the receiver,at the lower portion thereof, is the strainer and filter-plate L, abovewhich is a foraminous dome-shaped or convex diaphragm N, which dependsfrom the tube M,

Fig. 3 represents a horizontal sec' the upper portion of which is open,forming the vent'P. Fitted on said tube above the diaphragm. N istheYhanged tray Q, the bottom of which is perforated or foramnous, saidplate being adapted to be held at various heights in regard to theamount of'ground codec to be used by means of the. ring R and screw orpin R', which latter 'may be placed in either of the openings S in theside of the tube M one above the'otherr.

1 Depending fromY the bottom of the vessel B is the collar T, in theside of which is the angular slot U, which is adapted to receive the pinV as a bayonet-joint, said pin projecting outwardly from the sleeve W,which enters the collar T, and has a iiange X on its upper end, the samenormally resting on the bottom of said collar, thus limiting the descentof said sleeve and properly holding the same in position, it beingnoticed that said sleeve forms aV downward continuity of the pipe Haudits lower end freely enters an open-v ing in the lid G of themember-F, so that water iiowing from the vessel yB through the pipe Hpasses through the sleeve W and the opening in the lid G', and so entersthe receiver G. The pipe .I at the bottom of the receiver G freelyenters an opening in the lid K of the urn K, it being noticed that thecoee-maker F rests on said lid K'. NowA when it is desired to displacethe coffee-maker, either for receiving the codec-grounds or replenishingthe same with ground coffee or for other purposes, the sleeve W israised, whereby it withdraws from the lid G and is elevated above thesame. The pin V ascends in the vertical member of the slot U, and whenit reaches the horizontal member thereof it is turned thereinto, wherebythe sleeve is sustained in its elevated position. The coEee-maker maynow be raised, the pipe J at' the bottom thereof emerging from theopening in the lid K,thns discon nectingthe codec-maker from the urn andremoving it therefrom.

' Y designates the vent-pipe of 'the urn K, the same opening into the'interior thereof and having an outwardly-extending branch Y, so thatair can enter theurn to permit the discharge of the lfluid coee when thecock Y2 is opened, it being noticed that the head Y3 of said cock has asegment Z on the rear portion of its periphery, the same being IOOadjacent to the open end of the branch Y', sothat when the cock isclosed the said segment abuts against said end of the branch and closesthe same, and consequently the Vent-pipe, thus preventing the escape ofthe aroma of the coffee in the urn. When, however, the cock is opened,the said segment of the head moves from the end of the ventpipe anduncovers said end, whereby air may enter the Vent and supply theinterior of the urn for purposes hereinbefore stated. (See Figs. 4 and5.

The operation is as follows: The sleeve is raised, as hereinbeforestated, and the coffeemaker is disengaged from the urn. The lid G' isremoved and the tray Q withd rawn. The proper quantity of ground coffeeis now placed in said Vessel and rested on the diaphragm N, after whichthe tray is returned to its adjusted position, the cover of the vesselreapplied, and the coee-rnaker restored upon the urn. The sleeve W isnow lowered and inserted in the lid G', as in Fig. 1. It will now henoticed that the amount of water supplied from the tank A to themeasuringchamber B may be adjusted by means of the valve in the pipe C.The boiling water then iiows through the pipe H and sleeve W into thevessel Gr and passes through the ground coifee on the diaphragm N, thusmaking an infusion of the coffee. The valve J`is opened after the oo'eehas sufliciently infused and the beverage percolates and filters throughthe plate L, and so enters the urn K. It will be noticed that the waterentering the Vessel Gr passes through the tray Q in numerous streams orsprays, owing to the openings in the bottom of said plate, and so isthoroughly distributed over and upon the ground coffee. In some cases itmay be desirable to supply the vessel G with only a small quantity ofwater in order to saturate the ground coffee and then to admit a largersupply of water, which is sprayed upon the ground coee and caused todirectly circulate through the diaphragm N and the strainer and lterbelow the same.

The tank A, thechamber B, the vessel G, and urn K are suitably jacketedand may be insulated or packed in order to retain the heat within saidparts. The tank A and vessel B Will be supported in any suitable manner.

Various changes may be made in the details of construction withoutdeparting from the general spirit of my invention, and I do not,therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a coffee-making device, a primary heating-tank, a water-measuringtank and a coffee-making vessel detachably connected with saidmeasuring-tank.

2. In a coffee-making device, an urn, a coffee-making vessel mounted 'onsaid urn, a water-tank on said vessel, detachable liquidconveyingconnections between said urn and said vessel and between said vessel andsaid tank and Valves controlling the iow of liquid through both saidconnections.
